Saravôsh was once the greatest surface citadel of the Dark-Elves. In the year 736/2, the city was destroyed in a magical explosion which also created the Grôn chasm.
After Saravôsh was destroyed in the War of Wrath, the catastrophic magical energies expended in the explosion unleashed a horrific force of nature called "Ashfall;" a period of 100 years of black rain and darkness that covered most of eastern Corwyn, poisoning those lands forever.
One of the unexpected results of Ashfall was the "Taint." The Taint was actually an irreversible magical poisoning, that caused the appearance of the Dark-Elves to be altered forever; their skin turned black, their hair turned white, and they could no longer tolerate sunlight. Soon after, the Dark-Elves began to migrate underground, mostly through the Grôn Chasm they had accidentally created.
Battle of Saravôsh
The elven city of Saravôsh was the site of an epic battle in the year 736/2 that took place during the War of Wrath; fought between the Dark-Elves and Silvar-Elves.
During the battle, the Dark-Elves were defeated and, in a final act of desperation, unleashed a massive magical explosion. The explosion killed the Elf-King Ismelian, destroyed both opposing armies, as well as the entire city of Saravôsh.
The explosion also created an enormous chasm in the surface that came to be called Grôn. Only a lucky few escaped alive from this catastrophe, including Ismelian’s son; Talarion Brightstar.
